[PATCH v5 0/3] iavf: LLDP ptype and AVX2 ctx paths

[Ciara Loftus <ciara.loftus@intel.com>]

This series adds another way to detect LLDP packets in the Tx paths
of the iavf PMD, which is based on the mbuf packet type field. This is
in addition to the existing method of using a dynamic field. The series
also adds new AVX2 context descriptor Tx paths that support LLDP. Finally,
a deprecation notice is added to the documentation to flag that the
dynamic mbuf field method of LLDP packet detection will be removed in a
future release.

Patch 1 flags "CHECK:MACRO_ARG_REUSE" in checkpatch for the
IAVF_CHECK_TX_LLDP macro. This is a false positive because the inputs to
the macro are not reused in a way that would cause issues.

v5:
* Updated the documentation
* Made the "lldp mode" per-device rather than a global value. This is
necessary because the devarg is per-device unlike the global dynfield.
The mode is added to the iavf-specific flags in the ci_tx_queue struct
so that it can be read for each device on the datapath.

Ciara Loftus (3):
  net/iavf: support LLDP Tx via mbuf ptype or dynfield
  net/iavf: add AVX2 context descriptor Tx paths
